Perspectives of nonmajor undergraduate students on the impact of group discussions in learning physiology.

A 3-year study (2017-2019) was conducted to obtain the views of nonmajor undergraduate students about discussions in learning physiology. The teaching methods used were lecture only (lecture), group discussion alone (discussion), and a combination of lecture and discussion (lecture + discussion). Students were assigned homework in a textbook, and they did not have access to textbook/notes during discussions.

Impact of combination of short lecture and group discussion on the learning of physiology by nonmajor undergraduates.

This study assessed the impact of an "active learning" strategy employed alone or in combination with traditional lectures on the learning of mammalian physiology by undergraduate students. The study investigated the impact of three teaching strategies, namely ) traditional lecture, ) group discussion alone, and ) combination of lecture and group discussion. For all strategies, students were given homework in a textbook and they completed written assignments before each session.

Factors necessary to produce basoapical polarity in human glandular epithelium formed in conventional and high-throughput three-dimensional culture: example of the breast epithelium.

Background: Basoapical polarity in epithelia is critical for proper tissue function, and control of proliferation and survival. Cell culture models that recapitulate epithelial tissue architecture are invaluable to unravel developmental and disease mechanisms. Although factors important for the establishment of basal polarity have been identified, requirements for the formation of apical polarity in three-dimensional tissue structures have not been thoroughly investigated.

Phytates reduce uptake of leucine and glutamate but not lysine and glucose from the intestinal lumen of chickens: short communication.

An investigation into the influence of phytates on the in situ absorption of amino acids (lysine, glutamate and leucine) and glucose from the intestinal lumen of 3-week-old chickens was carried out. Birds were anaesthetised and the intestines exteriorised. Uptake of 5 mM of each nutrient over a 4-min period was measured in the presence of four phytate concentrations (0, 50, 250 and 500 mM).

Phytic acid increases mucin and endogenous amino acid losses from the gastrointestinal tract of chickens.

The influence of the form of phytic acid on the regulation of mucin and endogenous losses of amino acids, nitrogen and energy in chickens was investigated. Forty-eight 10-week-old male broilers were grouped by weight into eight blocks of six cages with one bird per cage. Birds received by intubation six dextrose-based combinations of phytic acid and phytase arranged in a 3 x 2 factorial consisting of phytic acid form (no phytic acid, 1.
